Has anyone compared these two speaker kits side by side? I'm interested in towers for music and HT. I am probably leaning towards sealed configurations as I will have a fairly low Q sealed subwoofer to round out the bass. Are there any other kits in the 300-450$USD (parts excluding cabinet materials) range that you would suggest (i.e. GR's Paradox 3's)? I'm not averse to bookshelf speakers although that would add more effort for construction of stands.
